Table of dangerous and safe days for conception, calculator

Planning a long-awaited pregnancy is quite a challenge. In order to solve it, you should know the table of dangerous and safe days for conception. The calculator can help to easily determine these days.

Planning a pregnancy is impossible to imagine without basic knowledge of the menstrual cycle. The latter consists of several successive stages or phases, each of them has its own characteristics. The main task of each of these phases is to prepare the female body for the upcoming conception. If the menstrual cycle is irregular, the female reproductive function is significantly reduced.

The pregnancy planning calendar allows women to quite easily navigate when another ovulation occurs - the most favorable period for conceiving a child. Entering the calendar of the beginning of the month, you can quite simply calculate the favorable time for conceiving a baby.

You can keep a calendar in different ways. The most obvious of them - graphic. In this case, the woman draws the dates in the calendar with different felt-tip pens or colored pens. As a rule, for convenience, the favorable for conception period is highlighted in green, and inappropriate days (first of all, monthly periods themselves) are red or black.

Maintain a pregnancy planning calendar should be quite carefully and responsibly. Any mistakes and inaccuracies that are made may cause the calculation of subsequent ovulation to be incorrect.

The best days to conceive, which are easier to get pregnant, are the days immediately before and after ovulation. The highest probability of pregnancy falls on the day of ovulation itself - at this time the egg cell is already ripe and ready to meet with the sperm.

Ovulation with a regular menstrual cycle occurs approximately in its middle. It should be noted that this is not the case in all cases, because ovulation is an extremely individual process. If the cycles are irregular or even anovulatory (without maturation of the follicle), it is almost impossible to calculate the exact date of onset of ovulation.

The table that follows presents the safest days for conception on the example of the 28-day and 32-day menstrual cycles.

Such a simple method of calculating days safe for conceiving is called calendar or mathematical. To perform it is quite simple, knowing the duration of the menstrual cycle. If the cycle is irregular, then the calculation is quite often with errors.

An often used alternative way of planning favorable days for conception is to determine ovulation by measuring basal temperature. To measure this figure should be in the morning, and even better to do it, while in bed. All obtained measurements must be recorded in a notebook or notebook - it will simply not forget them, as well as track the dynamics of changes.

The first half of the menstrual cycle is characterized, as a rule, by fluctuations in basal body temperature from 36.6 to 36.8 degrees Celsius. During ovulation, the indicator can reach a value of 37 degrees. Then the peak temperature decreases. Determining the basal body temperature will help determine the approximation of ovulation, and hence the onset of a favorable period for conceiving a child.

Ovulation can also be determined using:

• appearance of vaginal mucus and additional clinical symptoms (pain in the projection of the ovaries, enlargement and swelling of the breast);
• ready-made ovulation tests (by analogy with pregnancy tests), which can be performed at home;
• carrying out folliculometry (ultrasound of the ovaries).

Each method has its advantages and disadvantages. It should be noted that the admission of errors and inaccuracies is also possible, and in all ways. Many women in order to most accurately calculate the date of ovulation and safe days for conceiving a baby, use several methods at once.

In addition to favorable days for conceiving a baby, there are also dangerous during the menstrual cycle. At this time, the possibility of fertilization of the egg is significantly reduced. Doctors believe that the unfavorable days for conception are the period of menstruation itself (“monthly”), as well as several days before and after it. In order to understand why this is all happening, again, you should turn to biology.

During menstruation, the inner cellular layer of the uterus (endometrium) begins to reject. This feature is physiological and indicates a normal course of the menstrual cycle. At this time, the inner lining of the walls of the uterus is quite soft and loose. It is rather difficult to attach to such an egg surface, that is, the possibility of embryo implantation is rather low.

With each successive day after menstruation, the inner cell layer in the uterus begins to recover. In such a situation, the possibility of attaching a fertilized egg to the uterine wall is already increasing.

Immediately it is worth noting that menstruation is an unfavorable period for planning conception, however, the possibility of pregnancy at this time still exists. Such situations are found in gynecological practice quite often. Women who often have a pregnancy in the last days of their periods and immediately after them often turn to gynecologists.

The development of such a situation may be due to several reasons. First of all, these are features of the female body. The presence of diseases of the female genital organs or dyshormonal disorders contribute to "unplanned" ovulation. In this case, ovulation occurs earlier. A ripe egg cell is already ready to meet with the spermatozoon, and, despite the unprepared endometrium, such a meeting can still occur. In this case, there may be difficulties with the implantation of the embryo, but the onset of pregnancy is still possible.

Less favorable days for conception are also 3-4 days before and after the onset of menstruation. The table below shows most unfavorable days for planning conception with a 28-day and 32-day menstrual cycle.

At this time, the probability of pregnancy is significantly reduced, but still exists. The possibility of conceiving a baby in such a situation is due to the following factors.

• Short duration of the menstrual cycle. So, if it lasts less than 6 days, then during unprotected intercourse during the menstruation period, the onset of pregnancy is possible. This is due to the possibility of sperm to persist in the female genital tract for several days.
• Irregular sexuality. In this case, during sexual intercourse, a lot of sex hormones are released into the woman’s blood, which can provoke "spontaneous" ovulation. In this case, the egg can also be fertilized.
• Crash of the menstrual cycle. With an irregular and confused cycle, it is very difficult to accurately calculate on what day ovulation will occur. In this case, the possibility of the release of the egg during the start of the menstrual cycle also exists. A variety of causes can lead to failures in the ovaries - from banal stress to serious pathologies of internal organs.

It is also possible to calculate the favorable time for conceiving a baby through an online calculator. This simple method allows you to define dangerous and safe days when planning a pregnancy.

Using a calculator is quite convenient. To do this, you only need to enter the duration of the menstrual cycle and the date of the last menstruation. After a couple of seconds, the result will be ready. The work of any calculator for determining safe and dangerous days for conception is based on the calendar method of calculation.
